Thank you! It works. 
Sorry for my question.

I have still noticed before another problem with
"__attribute__((always_inline))".
I will write a bug report in a few days, as soon as I will reproduce it with a
small test case.
The bug actually accurs at a few positions in the STL with a error message
somewhat like "sorry unimplemented, could not inline". I could temporary fix it
with a few change in the STL. 

Are you interested if I post a new report for a performance issue in comparison
to ICL? This performance issue is the only one I know, that still prevents me
from prefering GCC to ICL.
